Suicide bombing in Kabul kills at least 4

An Afghan hospital official says at least four people have been killed and 20 wounded in a suicide bombing attack outside a Shiite mosque in the capital Kabul.

Hospital program coordinator Dejan Panic confirmed the casualties from the attack Friday.

Police officer Abdul Rahman says the attacker blew himself up on the street about 1,000 metres from the Hussainia Mosque. The attack took place just after Friday prayers as worshippers were on their way home.

A witness, Mir Hussain Nasiri, says the attacker was disguised as a sheepherder.

No one immediately claimed responsibility for the attack, which took place two days before the Muslim holy day of Ashura.
